Keras Reinforcement Learning Projects

By: Giuseppe Ciaburro

Overview of this book

Reinforcement learning has evolved a lot in the last couple of years and proven to be a successful technique in building smart and intelligent AI networks. Keras Reinforcement Learning Projects installs human-level performance into your applications using algorithms and techniques of reinforcement learning, coupled with Keras, a faster experimental library. The book begins with getting you up and running with the concepts of reinforcement learning using Keras. You’ll learn how to simulate a random walk using Markov chains and select the best portfolio using dynamic programming (DP) and Python. You’ll also explore projects such as forecasting stock prices using Monte Carlo methods, delivering vehicle routing application using Temporal Distance (TD) learning algorithms, and balancing a Rotating Mechanical System using Markov decision processes. Once you’ve understood the basics, you’ll move on to Modeling of a Segway, running a robot control system using deep reinforcement learning, and building a handwritten digit recognition model in Python using an image dataset. Finally, you’ll excel in playing the board game Go with the help of Q-Learning and reinforcement learning algorithms. By the end of this book, you’ll not only have developed hands-on training on concepts, algorithms, and techniques of reinforcement learning but also be all set to explore the world of AI.

OpenAI Gym

OpenAI Gym is a library that helps us to implement algorithms based on reinforcement learning. It includes a growing collection of benchmark issues that expose a common interface, and a website where people can share their results and compare algorithm performance.

OpenAI Gym focuses on the episodic setting of reinforced learning. In other words, the agent's experience is divided into a series of episodes. The initial state of the agent is randomly sampled by a distribution, and the interaction proceeds until the environment reaches a terminal state. This procedure is repeated for each episode, with the aim of maximizing the total reward expectation per episode and achieving a high level of performance in the fewest possible episodes.

Gym is a toolkit for developing and comparing reinforcement-learning algorithms. It supports the ability to teach agents everything...
